Reports non-final fields in enumeration types.
Non-final fields introduce global mutable state, which is generally considered undesirable.
<p><b>Example:</b></p>
<pre><code>
  enum Enum {
    FIRST("first"),
    SECOND("second");

    public String str;

    Enum(String str) {
        this.str = str;
    }
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  enum Enum {
    FIRST("first"),
    SECOND("second");

    public final String str;

    Enum(String str) {
        this.str = str;
    }
  }
</code></pre>
<!-- tooltip end -->
Use the `Ignore fields that cannot be made 'final'` option to only warn on fields
that can be made final using the quick-fix.
